CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 12/497,512, filed on Jul. 2, 2009, entitled ELECTRONIC TRANSACTION VERIFICATION SYSTEM WITH BIOMETRIC AUTHENTICATION. The above-identified application is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to credit and identity verification systems. More particularly, the present invention relates to credit approval and fraud protection at the point-of-sale for a transaction wherein biometric information is used to verify the identity of a person presenting a token for payment as an authorized user for the associated account and that the account is in order for the transaction. Transaction tokens can include a negotiable instrument, a credit card, a smart card, a loyalty card and a debit card. Information on the authorized accounts can be stored in either a token-based or tokenless electronic transaction system.

2. Description of the Related Art

There are devices known in the art that gather biometric data from persons for storage or for comparison with stored biometric data for purposes of identity verification. An example of storing biometric data for identity verification is U.S. Pat. No. 4,213,038 to Silverman, et al., for an access security system. Silverman, et al., discloses storing a fingerprint on a card, in either an actual print or “micropattern,” and the card is read by a control means. The fingerprint recordation is ancillary to the preferred function of the card which is identification based upon solely the microperforation of the card, which is not directly related to the fingerprint.

Check funds verification systems are also known in the art that allow merchants and others to verify that customers have funds available in a specific checking account. U.S. Pat. No. 5,484,988 to Hills, et al., discloses a check-writing point-of-sale system that provides for remote verification of funds availability. Hills, et al., is particularly directed to the purchase of goods through an electronic funds transfer.

U.S. Pat. No. 4,253,086 to Szwarcbier discloses a process and apparatus for positive identification of customers that is particularly disclosed as using a fingerprint on a credit card and comparing the fingerprint of the customer to that on the card, and selectively, with a master print on file. Szwarcbier also discloses a printed fingerprint card.

There are “smart cards” known in the art which include fingerprint identification means, such as U.S. Pat. No. 4,995,086 to Lilley, et al., U.S. Pat. No. 4,582,985 to Lofberg, U.S. Pat. No. 4,993,068 to Piosenka, et al., and U.S. Pat. No. 5,180,901 to Hiramatsu. All of these references disclose smart cards that have, at least, a stored fingerprint in a local memory (such as magnetic tape or integrated circuit) that interacts with a reading means at the point-of-sale to assist in customer identification.

An example of an actual fingerprint sensor is U.S. Pat. No. 5,745,096 to Hsumi, et al., which is for a surface-shaped sensor identification device. The Hsumi, et al. device is focused on the specific element of sensing and recording the fingerprint, as opposed to a complete identity verification system.

There are various types of biometric measurements in common use today. The types of biometric measurements include fingerprint verification, hand geometry, voice recognition, retinal scanning, iris scanning, signature verification, and facial recognition. Each biometric device and system has its own operating methodology. The process for any given individual usually begins with an enrollment process. The system captures one or more samples of the biometric. The samples are stored in a “biometric template” (also referred to herein as a biometric database), and are used for future comparison during authentication. Once enrollment and storage are complete, users authenticate themselves by matching the template against current input (“live data”). Comparison of the live data and the template results in a simple binary yes/no match.

Fingerprint verification is a well-known type of biometric measurement. If properly implemented, fingerprints provide high accuracy and at relatively low cost. Hand geometry measures physical characteristics of the individual's hand and fingers and is widely used in physical access control systems. Voice recognition remains difficult to implement. Despite recent advances in voice recognition technology, background noise, microphone quality, the common cold, and anxiety can alter the human voice enough to make voice recognition difficult, if not impossible. Voice recognition technologies include telephone authentication. Extraction and pattern matching algorithms embedded on computer chips are used to analyze voices. Retinal scanning is well established and highly accurate, however, it requires that the individual look directly into the retinal reader. Retinal scans shoot a low-intensity beam of light into the eye and record the pattern of veins in the eye. Iris scanning overcomes most of the problems of retinal scanners and does not require direct contact with the scanner, nor does it require the individual to remove eyeglasses. The technology works by scanning the unique random patterns of the iris. Unlike retinal vein patterns that can change over time, the iris is unique and does not change during a person's lifetime. Facial recognition systems measure characteristics such as the distance between facial features (e.g., pupil to pupil) or the dimensions of the features themselves (such as the width of the mouth). Neural network technology or statistical correlations of the facial geometric shapes are used with this kind of system. Signature verification is a relatively accurate system and is treated separately from the other forms of biometric systems described herein.

With fraudulent check losses alone reaching ten billion dollars annually, the banking industry is striving for ways to reduce these losses. Many proposals have been presented over the last five to ten years. One approach is placing the individual's fingerprint on a sticker and attaching the sticker to the check being presented. Among the more sophisticated approaches is the use of smart cards that have a chip containing biometric information of the account holder. The biometric information stored on the chip can be compared with the biometric information of the person presenting the smart card at the transaction location. However, these alternative methods of reducing fraudulent activity are not meeting the needs of industry. The use of fingerprint stickers are a deterrent for a less sophisticated forger, but the process of identifying the fingerprint on a sticker can take a long time in crime labs due to their backlog and their obvious priority of processing fingerprints obtained from crime scenes in which felonies involving violence occurred. Smart cards with embedded biometric chips are used with credit cards or debit cards, but still do not prevent the more sophisticated identity thief. The more sophisticated identity thief steals account information and then produces his own credit card containing his own biometric information embedded in the chip. When the identity thief presents his biometric information at the transaction location, the verification is being made against an already faulty biometric sample stored on the chip.

Tokenless point-of-sale payment processing systems have also been developed recently. One such system is described in U.S. Pat. No. 6,581,042 to Pare, et al. that uses biometrics obtained at the point-of-sale for verifying the identity of an individual as an authorized user of the tokenless payment system. Tokenless processing systems are intended to speed up the process of check-out at a transaction location by not requiring the person to present a physical token and by verifying the identity of the person presenting payment with the tokenless processing system. A drawback of current tokenless systems is that they only verify tokenless transactions. Tokenless systems do not verify the individual's identity or cross compare with a token-based transaction processing system when a transaction token is presented for payment at the point-of-sale. Therefore, unless the tokenless transaction system can be combined with verification of token transactions presented at the point-of-sale the tokenless transaction system does not prevent and is vulnerable to fraud. For example, a person registers with the tokenless processing system by providing account information and a biometric for identification during the processing of purchases at the point-of-sale by the tokenless processing system. The person registering with the tokenless system believes that all purchases will be authenticated by his biometric. However, this does not prevent a thief from either stealing or fabricating the registered person's physical token (e.g., check, credit card, etc.) and presenting it at a location that uses the tokenless processing system. Unless the physical token presented is checked against the tokenless processing payment system to determine if the account being accessed needs to be authenticated by a biometric, the physical token could be accepted without verifying the identity of the person presenting the token for payment.

SUMMARY

Various embodiments described herein, combine the use of valid biometric samples obtained from authentic identifications (IDs) with biometric samples provided by a person at a transaction location, thereby verifying that the biometric information presented for a transaction is a valid biometric for a particular person. In addition, the ID and the biometric sample can also be checked against known invalid users. Although it is possible for someone to counterfeit what is believed to be the authentic ID, in such cases, the identity thief provides an actual fingerprint that has been taken and placed on the token or on the transaction slip. When the token is returned to the transaction location as forged, counterfeit, stolen, etc., the fingerprint is entered into the database of known invalid users, thus preventing any further identity theft activity by this person on the verification system. Various embodiments add additional safeguards, such as verifying the ID with information from the state. This ensures that an ID has not been altered, and is in fact an authentic state-issued ID (e.g., driver's license). Another such safeguard is verifying the information at the processing center of the token with the original information that a bank or token company obtained at the creation of the bank or token account.

Various embodiments include a verification system for check/negotiable instruments or other form of tokens, which has the ability to scan the information from negotiable instruments such as the magnetic ink character recognition (MICR) line, and gather biometric data such as fingerprints. The system alternately and/or additionally scans driver's licenses or other identification cards, and obtains and transmits a signature of a customer, preferably all occurring at a transaction location (e.g., point-of-sale) for purposes of identity and fund verification. However, the electronic transaction can occur at places other than a point-of-sale. For example, the electronic transaction can occur over the Internet, as part of an Internet-based transaction and include transmission of biometric data or signatures for user verification. Therefore, in general, transaction location refers to the place where the user or customer enters his information, such as account data or biometric data into the electronic transaction verification system. The verification system preferably digitizes various indicia of the check, the preferred indicia being the magnetic ink (MICR line) on the check, tendered by the customer at the transaction location, and transmits the data through a communications medium, to a processing system including a negotiable instrument information database, whereby the inputted data is compared with an existing database of information to determine if the customer at the point-of-sale is in fact authorized to use the account, and if the account is in satisfactory condition for transaction approval. The communications medium can be a broadband connection, a dial-up connection, a direct communications link, a satellite link, or fiber optic cable or any other communication link that allows communications between a transaction location and a central or local processing system and database.

In this exemplary embodiment, the verification system alternatively includes a device and method for recording and/or transmitting a biometric measurement of the customer at the location of the transaction and, in the case of a fingerprint biometric, printing the fingerprint on the negotiable instrument, either in actual or digitally encoded form, such that the fingerprint can be later checked against a biometric database of existing fingerprints at such time as the instrument is processed at a bank, which provides an added means of security in the event that fraudulent activity has been discovered between the time of receiving the token at the transaction location and the time it is presented at the processing center. If the system includes a device for scanning an information card that contains biometric data, such as a proper fingerprint printed on a driver's license, and/or signature, then the fingerprint and signature of the user can alternatively be compared to the recorded data on the card, in addition to or instead of, transmission of the various databases.

In another embodiment of the verification system, a negotiable instrument or other token is swiped and the fingerprint is simultaneously taken and digitized whereby the combined data is transmitted to a central (or local) processing system that includes an account information database and a biometric database, and the transmitted data is compared with identification data already on file, and the central (or local) processing system determines if the identification data of an authorized user on file matches with the transmitted data from the user at the transaction location. Local system, in the present context refers to a system that is in physical proximity to the transaction location (e.g., same store). The system then returns the results of the decision on approval to the transaction location. A device at the transaction location displays the decision data and/or prints out a hard copy indicating whether the negotiable instrument/token was approved or denied.

As is well known in the banking industry, the MICR line on a check includes the bank routing number, account number, check number, check amount, and other information, that can be printed near the bottom of the check in magnetic ink in accordance with generally applicable industry standards. In operation, the central (or local) processing system receives data from the transaction location and then determines if the “ABA” magnetic number on the MICR line of the check is a valid number, if the fingerprint data is that of an account owner authorized to use that account, and/or if the signature is that of the authorized account owner, whereby any negative response to these decisions preferably causes return of the data indicative of the negative response to the transaction location. Upon affirmative indications in the decisions, the central (or local) system retrieves the frequency of the account accesses to determine if the current requested access is in excess of a pre-determined limit of an allowable number of accesses. If the current access is in excess of the pre-determined allowable limit, then the data is returned to the transaction location indicating the unacceptable request to exceed the limit, and thus, disapproval of the transaction. If the current access is not in excess of the allowable determined limit, then the verification of the check is approved and such verification is used to update the frequency of account access database, and the approval is returned to the transaction location. Various account conditions can be used, alternatively, to verify the condition of an account. Such conditions can include “outstanding checks,” “returned checks,” and “account closed” among others. For example, if there are outstanding checks on the system for a user's account, then in various embodiments, an indication can be returned to the transaction location that the user's account is not in condition to satisfy the negotiable instrument. Likewise, if the token is a credit card, debit card, loyalty card, smart card or similar-type token, the condition of an account can include “exceeding credit limit,” unpaid balance,” “insufficient funds,” etc.

In a further exemplary embodiment, the transaction database and/or the biometric database within a tokenless payment system can be used to verify or authenticate the person presenting a token at the transaction location. The token being presented at the transaction location is swiped obtaining the necessary account information and sent to a processor for comparison with account information stored in the transaction information database within the tokenless processing system. If a match occurs with account information stored in the transaction database of the tokenless system, the token system then requires the token to be authenticated by a biometric. The biometric information is then sent either separately or in parallel with the transaction information to the tokenless system for approval.

The verification system preferably includes the capability to provide reports on user/customer activity to a merchant or business upon request. The merchant directs an inquiry to the central (or local) system which is in communication with a series of databases and which preferably includes databases indicative of: a number of transactions for a specific account; the location of the transactions for such account; and a user/customer list and relevant data associated with the user/customer. Depending upon the inquiry generated from the merchant, the main (or local) system retrieves the requested information to generate a report on a specific customer, and then returns the report to the merchant.

Alternatively, the verification system can be used in conjunction with a bank proofing machine during batch processing of checks. When the proofing machine scans the magnetic number from the check, the identification data imprinted on a check at the transaction location is compared with account owner identification data as recorded and maintained by the bank to determine if the correct account owner submitted the check. The verification system can also be used in conjunction with an Electronic Check Exchange (ECE) system in which the check information is exchanged electronically, in lieu of or in addition to the exchange of paper checks. For forward presentment, an ECE system is usually referred to as an Electronic Check Presentment (ECP) system. The verification system can be used in conjunction with Automatic Clearinghouse (ACH) processing systems. Furthermore, the verification system can be used in conjunction with a token processing system such as a credit card or debit card processing center to verify the information read from the magnetic strip on the token with information recorded and maintained by the credit or debit card processing center.

DETAILED DESCRIPTION OF THE VARIOUS EMBODIMENTS

The following detailed description is directed to certain specific embodiments. Those skilled in the relevant art will recognize that many changes can be made to the embodiments described, while still obtaining the beneficial results described herein. It will also be apparent that some of the desired benefits of the various embodiments described herein can be obtained by selecting some of the features of the embodiments described herein without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present invention are possible and may even be desirable in certain circumstances and are a part of the present invention. Thus, the following description is provided as illustrative of the principles of the various embodiments of the electronic transaction verification system and not in limitation thereof, since the scope of the present disclosure is defined by the claims.

Referring now in greater detail to the drawings, in which like numerals represent like components throughout the several views, FIG. 1 illustrates a block diagram of an exemplary embodiment of the verification system illustrating an electronic transaction verification unit 10 in communication with a central processing system 12 that includes an identification database 14. Embodiments of the various electronic transaction verification systems usable with systems and methods of the present disclosure are described in the co-pending U.S. patent application Ser. No. 12/050,772 titled “Electronic Transaction Verification System” filed on Mar. 18, 2008, published as U.S. Publication No. 2008/0156866 on Jul. 3, 2008, which is incorporated by reference herein in its entirety. The identification database 14 can include a number of databases used in the identification process such as a biometric database of known customer data, as well as a separate database of known invalid users. The database of known invalid users can be established by correlating a biometric presented at a transaction location that is used with a fraudulently obtained transaction token, and storing the biometric as invalid. Central processing system 12 can be a main system remote from the transaction location. While a check is disclosed as one type of token to be processed in an exemplary embodiment of the present inventive system, other tokens can be processed in the same manner as disclosed herein. Negotiable instrument, as the term is used herein is defined in Article 3 §104 of the Uniform Commercial Code. An instrument is negotiable if it is: (1) a written instrument signed by the endorser or maker; (2) an unconditional promise to pay a certain amount of money, either on demand or at a future date; and (3) payable to the holder or bearer. Examples of negotiable instruments are checks, bills of exchange, and promissory notes. A check as used herein means a draft, payable on demand and drawn on a bank, or a cashier or teller's check. This is the customary definition of a check. The exemplary embodiment of the electronic transaction verification unit 10 is comprised of, at least, a check scanner or token reader 16 and a biometric data-gathering device 18, such as a fingerprint recording device.

Many check scanning devices are known in the art that scan the magnetic ink on the bottom of checks and such devices range in use from point-of-sale devices to scanners used at banks, where the more advanced devices are referred to as bank “proofing” machines. However, such device alternately and/or additionally includes the capability of video digitization of the check or gathering of other characteristics of the check that are useful for comparison.

The biometric recording device 18 preferably digitizes the fingerprint of a customer at the point-of-sale for transmission to a remote biometric database. Many devices for digitization and transmission of fingerprints are well known in the art, such as the devices of digital biometrics. Other biometric devices such as retinal scanners and voiceprints are alternately and/or additionally used with, or in lieu of, the exemplary fingerprint scanner. Such biometric devices are commercially available and adaptable for use with the various embodiments of the electronic transaction verification system described herein. The electronic transaction verification unit 10 also preferably includes a card reader/scanner, such as a driver's license scanner 20 which scans information from a driver's license, which is especially useful in states that put information, such as fingerprints, in a computer-readable medium such as a magnetic strip (e.g., a California license) or a bar code (e.g., a Georgia license) on the driver's license. When the license contains this information, the electronic transaction verification unit 10 can perform an initial comparison between the biometric recorder device 18 and the device's license scanner 20 for determination of the user's/customer's identity, in addition to or instead of, transmitting biometric data to the biometric database of the central processing system 12. The information gathered from the license scanner 20 can also be verified with information licensed from a state division of motor vehicles in order to authenticate a driver's license. Finally, the electronic transaction verification unit 10 preferably includes a signature-taking device 22 that allows a customer to write his or her signature on the device that then encodes the signature into digital format for transmission. Such transmissions can occur with or separately from the transmission of the check identification and biometric data. There are many devices known in the art that allow a signature to be digitized for storage and comparison, and any of such devices will work satisfactorily in the present inventive system.

The electronic transaction verification unit 10 is preferably a computer platform which has the capability to receive, digitize and process the incoming data from the devices, shown by block 24, for transmission to a central processing system 12. The central processing system 12 can be remotely located from the electronic transaction stations or can be at the same location as the electronic transaction station, e.g., an in-store central processor and database connected to electronic transaction stations by a local area network. The other devices can be integrated with the computer platform of the electronic transaction verification unit 10, however, the devices can also be independent from the computer platform as long as they are in connection with the electronic transaction verification unit 10 sufficient to transmit and have received by the unit 10 the relevant data from the devices. The central processing system 12 is in connection with, at least, an identification database 14, which at a minimum contains the relevant specific identification data related to various checking and/or credit accounts. The identification database 14 can be a hard drive on the central processing system 12, computer platform, or other type of memory device located either locally or remotely, but in connection with, the central processing system 12. Thus, in a basic form, the embodiments described herein solely generate and record identification data of the customer relevant to a single sale and acceptance of a token at a transaction location through recordation of the specific token identification and biometric data of the customer at the transaction location, which is then transmitted by the various devices of the electronic transaction verification unit 10 for recordation. When the simple recordation of the event is effected, it is preferable that the electronic transaction verification unit 10 output a fingerprint (or other biometric data) for inputting on the specific check, negotiable instrument, or in conjunction with another type of token at the transaction location, shown by output 26, either in actual or digitally encoded form, whereby this identifying characteristic of the person cashing or tendering the check is contained upon the check itself and banks processing the check have the capability to compare that imprinted fingerprint with fingerprints on file for the actual account holders, if necessary. However, the printing of the fingerprint on the check or in conjunction with the token (e.g., credit card receipt) can be alternately and/or additionally used in any embodiment of the present inventive verification system.

Various embodiments of the system described herein can be used to verify, validate and/or process various transaction instruments issued by an issuing entity to a receiving entity. As used herein, a transaction instrument can include but is not limited to personal checks, payroll checks, cashier or teller's check, traveller's check, negotiable instruments, a draft payable on demand and drawn on a bank, money orders, credit cards, debit cards, decoupled debit cards, loyalty cards, check cards, smart cards, flash drives, usb thumb drives, usb pen drives, usb pin drives, memory stick, food stamps, tokens, etc. In various embodiments, the transaction instrument or a transaction token can include a physical object, apparatus or device that holds information related to one or more financial accounts associated with a user. In some embodiments the transaction instrument or transaction token can include a physical device that is enabled with radio frequency identification (RFID) tag that holds information associated with or representative of one or more financial accounts associated with a user. As used herein an issuing entity can be any entity that issues the transaction instrument. Examples of issuing entities include but are not limited to an individual, an employer, a corporation, municipal, state and federal government, etc. As used herein, a receiving entity can be any entity to whom the transaction instrument is issued by the issuing entity. Examples of a receiving entity are individuals, employees, corporations, partnerships, etc. As an example, in some embodiments, the receiving entity is an employee of the issuing entity which is an employer or a company. In this example, the employee can receive a payroll check or a reimbursement check from the employer.

In various embodiments, the receiving entity can exchange the transaction instrument for money, goods and/or commodities at a transaction facilitating entity. As used herein, a transaction facilitating entity is an entity that accepts and processes various transaction instruments described above and exchange these transaction instruments money, goods and/or commodities. Examples of transaction facilitating entities are banks, retailers, super-markets, check cashing companies, payment processing companies, etc.

FIG. 1A is a block diagram of an exemplary embodiment of the verification system illustrating an electronic transaction verification unit 10 in communication with a central processing system 12 and a plurality of information stores 17 that can be used process various transaction instruments at a transaction location. In various embodiments, the transaction location can include the transaction facilitating entity's premises. As described above, in some embodiments, a part of the verification system illustrated in FIG. 1A can be located at the transaction location and another part can be located at a location remote to the transaction location. For example in some embodiments, the electronic verification unit 10 can be provided at the transaction location, while the central processor 12 and the plurality of information stores 17 can be provided at a location remote from the transaction location and accessed for example, via a network such as the Internet. However, in other embodiments, the central processor 12 and the plurality of information stores 17 can be provided at the transaction location. Although, a plurality of information stores 17 is illustrated in FIG. 1A, a single information store can also be used in some embodiments. As described herein, the plurality of information stores 17 can include databases, relational databases, lists or other types of data stores that can be accessed electronically.

Upon presentation of the transaction instrument, the verification system can scan and/or read the transaction instrument to obtain information encoded therein by a reading device 16 configured to scan and/or read the transaction instrument. In various embodiments, the reading device 16 can be a check scanner or a token reader as described above. In various embodiments, the encoded information can include but is not limited to name of the receiving entity, “ABA” number, account number, card number, serial number or check number, date of issue of the transaction instrument, expiry date of the transaction instrument, the value of the transaction instrument, the amount specified on the transaction instrument, etc.

The verification system can also obtain biometric information from the individual presenting the transaction instrument using the biometric data gathering device 18 described above. In various embodiments, the biometric information can be at least one fingerprint, a retinal scan or some other biometric signature. The encoded information and the biometric information gathered by the verification system can be transmitted to the central processor 12 by an electronic communication system as shown by the logic block 28.

In various embodiments, the electronic communication system can include a wired or a wireless network. In various embodiments, the gathered information may be transmitted to the central processor 12 in substantially real time such that central processor 12 receives the gathered information in less than approximately 1 minute, 2 minutes, 3 minutes or 5 minutes after the transaction instrument is scanned or read. In some embodiments, the gathered information may be transmitted to the central processor 12 over a time period which extends over a few hours or a few days. As described above with reference to FIG. 1, the verification system may also scan information from the driver's license of the individual presenting the transaction instrument using a driver's license scanner 20 and transmit the driver's license information to the central processor 12 in addition to the encoded information from the transaction instrument and the biometric information.

The central processor 12 is configured to access one or more information stores 17 to verify, validate and/or process the received information. For example, in some embodiments, the central processor 12 can access data and/or one or more lists stored in the one or more information stores 17. The plurality of information stores 17 and the data stored therein can be maintained by a transaction validating entity that verifies, validates and/or processes transaction instruments. Examples of transaction validating entities are banks, financial institutions, payment processing companies, check clearing companies, etc. In various embodiments, the transaction facilitating entity and the transaction validating entity may be same.

The data and lists can be previously provided to the transaction validating entity by an individual or a company associated with the issuing entity. In various embodiments, the lists can include information associated with a plurality of transaction instruments issued by the issuing entity and biometric information of one or more individuals associated with or representing one or more receiving entities. In some embodiments, the individual whose biometric information is included in the list can be the receiving entity. In other embodiments, the individual whose biometric information is included in the list can be a person authorized by the receiving entity to act on its behalf. In various embodiments, the issuing entity can obtain the biometric information while registering or enrolling the receiving entity in a transaction verification system such as a payroll program whereas in other embodiments, the biometric information gathered the first few times a transaction instrument is presented can provide a template by which future transactions are verified. A method of enrolling individuals associated with or representing one or more receiving entities in a transaction verification system is illustrated in FIG. 1B and further described below.

If the encoded information obtained by the reading device 16 matches an item in one or more information stores 17 and the biometric information obtained from the biometric data gathering device 18 matches the stored biometric information for the individual associated with the receiving entity to whom the transaction instrument was issued, then the transaction validating entity can make a decision to approve the transaction. However, in some embodiments, if the obtained encoded information does not match any item in the one or more information stores 17 and/or the biometric information does not match the stored biometric information for the individual associated with the receiving entity, then the transaction validating entity can reject the transaction. Alternatively, if the obtained encoded information and/or the biometric information does not match one or more entries in the one or more information stores, then the transaction validating entity can seek approval from the issuing entity prior to making a decision on the transaction.

The decision can be returned to the transaction location as illustrated by the logic block 48. In various embodiments, the decision can be output to an output device as shown in the output block 21. In various embodiments, the output device can include but not be limited to a display device or a printing device or both. Other types of output devices known to persons having ordinary skill in the art can be also used. In various embodiments, the above described method can performed in substantially real time such that a decision on the transaction instrument can be returned to the transaction location and output to the output device in less than approximately 1 minute, 2 minutes, 3 minutes or 5 minutes from the time the transaction instrument is read or scanned. In some embodiments, the decision on the transaction instrument can be returned to the transaction location in a time period which extends over a few hours or a few days from the time the transaction instrument is read or scanned.

FIG. 1B illustrates an embodiment of a method to enroll users in a transaction verification system. In various embodiments, the users of the transaction verification system can be individuals associated with or representing one or more receiving entities. In various embodiments, the transaction verification system can have some similarities with various fraud detection and prevention systems such as POSITIVE PAY.

To enroll users in the transaction verification system, an issuing entity or an individual or company associated with the issuing entity gathers user information as shown in block 4. The gathered user information may include information such as name, identification number (e.g., social security number, employee identification number, etc.), date of birth, address, etc. The gathered user information can also include biometric data associated with the user. The biometric data as referred to herein includes a characteristic of the user's body. For example, biometric data can include but not be limited to related to any one or more of a user's fingerprint, eye retina and iris, handprint, voice pattern, facial pattern, etc.

The gathered user information can be transmitted to the central processor 12 as shown in block 6. The central processor 12 can store the gathered user information in one or more information or data stores 17. As discussed above, in various embodiments, the one or more information stores 17 can be maintained by the transaction validating entity.

In various embodiments, when the issuing entity issues a transaction instrument or token to the user, information associated with the transaction instrument or token can be transmitted to the central processor 12 as shown in block 8 of FIG. 1B. The information associated with the transaction instrument or token can include but is not limited to name of the user, transaction amount, date of issue, expiration date, etc. In various embodiments, the information associated with the transaction instrument or token can be encoded in the transaction instrument or token. The transaction instrument or token information can be stored in an information store that is different from the information store that includes the user information. The user information store and the transaction instrument or token information store can have a common field which links the transaction instrument or token issued to an user with the information (e.g., biometric information, etc.) associated with that user. However, in other embodiments, the information associated with the transaction instrument or token can be stored in the same information store that includes user information.

In various embodiments, the central processor 12 may send a confirmation as shown in block 11 of FIG. 1B. In some embodiments, the confirmation is sent to the system that transmits the user information and/or the transaction instrument or token information. The confirmation message can include confirmation of the receipt of the user and/or the transaction instrument or token information; successful enrollment of the user; successful update of the information stores, etc.

The above described method of enrolling users in a transaction verification system can be used for example by a company that has several employees and issues payroll checks to the employees. In this example, the users of the transaction verification system can be the employees. The employees can be enrolled in the transaction verification system at the time they accept employment with the company subscribing or using the transaction verification system. Subsequently, every time the company issues payroll checks to its employees, information associated with the payroll checks, such as the payee on the check, check number, amount of the check, etc. can be transmitted to the central processor 12.

When the user presents the payroll check for encashment, information from the payroll check and the biometric data of the user can be compared with the corresponding information stored in the one or more information stores and the results of the comparison can be used to accept or reject the payroll check. A person skilled in the art can recognize that the users can be enrolled in the transaction verification system only once and it is not required to transmit the user information every time a payroll check is issued to the user.

The above described method of enrolling and verifying transaction instruments or tokens can also be used by municipal, state and/or federal government agencies that provide assistance to the public such as unemployment benefits, food stamps, social security benefits, disability benefits, medical benefits, etc.

FIG. 2 illustrates an alternative embodiment of the electronic transaction verification unit 10 in communication with a central database 30 such that the central database 30 allows the data stream of the electronic transaction verification unit 10 to be acted upon by decision block 32 to determine if the token verification is approved or denied, and then returns the approval decision to the electronic transaction verification unit 10. In such embodiment, the computer platform receives, processes, and transmits the data of the various devices, shown by logic block 28, to the processor 12 for comparison with information stored in identification database 14 included in the central database 30, via a communications link, for a simple comparison step to determine approval. The central database 30 can include a customer account information database (i.e., transaction information database), a biometric database of known customer biometric data, as well as a separate database of known invalid users. The database of known invalid users can be established by correlating a biometric presented at a transaction location with a fraudulently obtained transaction token and storing the biometric as invalid.

At the central processor 12, the incoming data is compared, either in parallel with or separately with token identification data, with the existing known data for authorized users of accounts stored in central database 30, shown by decision block 32, and an approval is made as to whether or not to accept the token. Either a yes decision 34 or a no decision 36 on approval is then re-transmitted back to the computer hardware platform 28 of the check verification unit 10. While the check verification unit 10 is shown in communication with a processor 12 and database 30 remotely located thereto, it is not necessary that the central processing system 12 or the database 30 be located remotely to the electronic transaction verification unit 10. In fact, the electronic transaction verification unit 10 and central processing system 12 can be self-contained at the transaction location whereby the central database 30, or the account information and biometric databases are continually updated within the electronic transaction verification unit 10 through either a data connection to a master database or through periodic manual updates from storage media such as floppy disks or CD ROMs. In such an embodiment, the electronic transaction verification system is preferably self-contained and includes all the necessary devices for scanning drivers' licenses 20, gathering biometric data (e.g., fingerprints) 18, or scanning checks/reading tokens 16 (gathering check or token information data) within one unit including the system.

FIG. 2A illustrates another embodiment of an electronic verification unit 10 wherein the central processor 12 is configured to associate biometric information obtained when a transaction instrument is presented to a verification system with an information encoded on a transaction instrument if no biometric information has been previously associated with the encoded information on the transaction instrument. For example, if the central processor 12 determines that no biometric information is associated with encoded transaction instrument information in the central database 30 (as shown in the logic block 23), then a NO decision 27 is made at the logic block 23. The central processor 12 then proceeds to associate the biometric information with the encoded information. If however, the central processor 12 determines that biometric information was previously associated with the encoded information, then the central processor 12 can proceed to make a decision on whether to accept or reject the transaction instrument (as shown in block 32). As discussed above, with reference to FIG. 2, either a YES decision 34 or a NO decision 36 on approval is then communicated to the computer hardware platform 28 of the check verification unit 10.

In some embodiments, if the encoded information and/or the biometric information obtained when the transaction instrument is presented to the verification system does not match the previously stored encoded information and/or biometric information which is associated with the transaction instrument, then the central processor 12 can add the transaction instrument information and the biometric information to an information store that includes a list of invalid users and/or transaction instruments.

FIG. 3 is a flow chart of an exemplary embodiment of the processing logic of the electronic transaction verification system showing the electronic transaction verification unit 10 where a check or token is swiped, shown by logic block 38, and a fingerprint is taken, shown by logic block 18, with the fingerprint then being digitized, shown by logic block 19. Both the check information data and the biometric fingerprint data are unified at the transmitting data platform, shown by logic block 40, for parallel transmission. The transmitted data then reaches the central processing system 12 that is in communication with a check or token account and biometric identification database 14 such that a decision is made within the central processing system 12 in regard to check or token approval. As discussed previously, the identification database 14 can include a plurality of databases used in the identification process. One of these is the biometric database of known customer data. An additional biometric database of known invalid users can also be established. The identification database 14 collectively refers to the one or more biometric databases. The central processing system 12 performs a decision determining if the check/token information and biometric data are consistent with an authorized user for the account against which the check is drafted or token is provided, shown by decision block 42, whereby a yes decision 44 or a no decision 46 is returned to the transaction location, shown by logic block 48. Upon return of the data from the central processing system 12, the data indicative of the decision is displayed, shown by display block 52, and/or a hard copy is printed out, shown by document block 50, indicative of the decision made, and alternatively, the grounds for acceptance or rejection.

Various embodiments described herein accordingly utilize an inventive digital process whereby a dataset originates from the transaction location from the electronic transaction verification unit 10, shown by logic block 54, as shown in the processing logic flow chart of FIG. 4, and is preferably processed on the central processing system 12. A decision is made as to whether information on the MICR line (e.g., “ABA” number) or on the token is valid, shown by decision block 56, and then a decision is made as to whether the biometric data (e.g. fingerprint) is that of an authorized user, shown by decision block 62, Next, a decision (optional) is made as to whether the signature presented is that of an authorized user, shown by decision block 68. An authorized user is an individual authorized to use the system. An authorized user can be the account owner. An authorized user can also be the payee of a check, a subsequent payee or any other individual authorized to access an account in the system. Affirmative responses to these decisions in blocks 56, 62 and 68, shown by “yes” arrows 58, 64, and 70, respectively, preferably allow further processing of the data. Negative responses, shown by arrows 60, 66, and 72, respectively, preferably effect a return of data to the transaction location indicating that the transaction is disapproved, shown by block 74.

Once affirmative responses have been received to decisions 56, 62, and 68, then the data can be further processed by accessing a frequency of access database 78 which has information on accounts based upon the numbers of inquiries to the system for a specific account, shown by logic block 76, and such information is maintained and updated in the frequency of account access database, shown by database 78, which can be either integrated with or remote to the central processing system 12. Then a decision is made as to whether the current access is in excess of a predetermined allowable amount of access inquires to the system for a specific account, shown by decision block 80, and if the current access is in excess of the allowable pre-determined amount, shown by “yes” arrow 82, then the data is returned to the transaction location indicating that the requested access exceeds the allowable amount, shown by logic block 84, and thus that the transaction is disapproved. Otherwise, if the current access is not in excess of the allowable pre-determined amount, shown by “no” arrow 86, then the electronic transaction verification request is approved, shown by logic block 88. Other measures can also be used in lieu of, or in addition, to these steps, to verify the condition of the account. Several of the measures were identified above.

Upon approval, the information regarding approval is transmitted, shown by arrow 90, to the frequency of account access database 78 for updating of the records contained therein. The information regarding the approval of the electronic transaction is then returned to the transaction location and electronic transaction verification unit 10, shown by logic block 92.

The steps of the processes set forth in FIG. 4 are preferably performed by software being executed on the computer platform including the central processing system 12, located either at the transaction location and integrated with the electronic transaction verification unit 10, or located remotely thereto. One of skill in the art of computer programming can determine from the present disclosure and the flow charts disclosed herein the objects sufficient to write a program for the computer platform sufficient to perform the tasks as disclosed herein.

In the exemplary embodiment illustrated in FIG. 7, the transaction database 33 and/or the biometric database 35 within a tokenless payment system can be used to verify or authenticate (decision block 37) the person presenting a token for payment at the transaction location. The token being presented at the transaction location is swiped (logic block 16) obtaining the necessary account information and sent to a processor 15 for comparison with account information stored in the transaction information database 33 within the tokenless processing system. If a match occurs with account information stored in the transaction database 33 of the tokenless system, the token system then requires the token to be authenticated by a biometric (decision block 37). The biometric information is gathered (logic block 18) and then sent either separately or in parallel with the transaction information (logic block 28) to the tokenless system for approval.

If the account information is sent to the tokenless system transaction processor 15 and there is no existing account in transaction database 33, then the transaction information would be processed by the normal procedures for handling the token at the transaction location by electronic verification unit 10. If the transaction location normally requires a biometric for the processing of a token then the check/token account information 16 and the biometric information 18 can be gathered at the onset of the transaction and the tokenless databases 33, 35 then would be additional databases that would be checked. The transaction information database 33 and the biometric database 35 can be the same databases for both token-based and tokenless systems. Likewise, the central processor 12 handling token-based transactions (arrow 29) can be a separate processor or the same processor handling the tokenless transactions.

In one embodiment, the electronic transaction verification system preferably includes the capability to return a report to a merchant/vendor upon request, as shown in FIG. 5. As so embodied, an inquiry and/or request is made from a merchant directed towards the central processing system 12, shown by logic block 94, which requests a specific report or series of reports. The central processing system 12 preferably includes access to a variety of databases 96, which preferably contains separate databases including a database indicative of a number of checks cashed for a given account, shown by database 98, locations of checks cashed for a specific account, shown by database 100, and a database containing various information regarding the customers of the account, shown by database 102. The central processing system 12 selectively accesses and interacts with these databases in response to the inquiry from the merchant at logic block 94, and generates a report on the specific customer or customers, shown by processed data logic block 104. The processed data then is returned in report form to the specific merchant, shown by logic block 106, which made the inquiry and request to generate the report. Such information generated by the verification system can prove highly informative as to customer trends such as drops in frequencies of purchases, customer dissatisfaction, or other trends that can then be effectively targeted by marketing efforts.

The present inventive electronic transaction verification system further provides that after the biometric identification data, such as a fingerprint, has been imprinted on the check, the system can alternately and/or additionally be used at a bank in conjunction with the proofing machine to determine if the biometric identification data on the check is that of the account owner. As shown in FIG. 6, the biometric data from the biometric scanning device 110, preferably at the transaction location 112, is sent, either electronically or physically, to the proofing machines for checks or negotiable instruments 114, typically at a bank processing center 116. In the past, checks were typically sent physically to a bank or processing center and the magnetic line of the check physically scanned by the proofing machine 114. Currently, many checks are being truncated electronically and the information contained therein is being processed directly or indirectly by host computers at the bank or processing centers.

In the embodiment shown in FIG. 6, the biometric data is printed on the check by the biometric scanning device 110 and the printed biometric data is scanned, and thus gathered, in addition to the magnetic numbers of the check. A comparison step preferably occurs within the proofing machine 114 during the batch processing and scanning of the magnetic numbers of the checks for transfer of funds from the accounts. The biometric data is retrieved and updated from a first biometric database 118 that contains the biometric data for known customers having accounts. The proofing machine 114 also preferably perform a comparison step with a second biometric database 120 containing biometric data for known invalid users who have perpetrated, or attempted to perpetrate, fraudulent activity with regard to tendering checks/negotiable instruments. Databases 118 and 120 can reside on the proofing machine 114, or can be located remotely. Such information in biometric database 120 is preferably also accessible by the biometric scanning device 110 at the transaction location 112 for updating and comparing, either separately from or in conjunction with, the proofing machine 114. If the check/negotiable instrument being compared was tendered fraudulently, the biometric database 120 is useful for determining the perpetrator's actual identity, and comparison between databases 118 and 120 can also be made for identity determination. In that regard, biometric database 120 is also accessible by central processing system 12, identification database 14, central database 30, as well as electronic transaction verification unit 10 for detection of known fraudulent users.

The embodiments described herein can be utilized in a variety of forms with a variety of sources of information other than those described in detail herein. As an example, the electronic transaction verification system can be interfaced to various transaction and identification information databases containing customer account information and biometric information.
